I am new to Matlab from the Python domain, and am looking to write a short for loop which will take all .wav files ( I have many .wav files in a single folder for training data for a machine learning project). I want to iterate through each .wav file in the folder and produce a spectrogram and save each spectrogram to the folder with the same name as the original .wav file.

All files are the same length (3 seconds) and are all sampled at 500kHz.

This should be straight forward but I am struggling a bit as this is my first time on Matlab
